What is meant by the term "routing table"?

The term "routing table" refers to a database maintained by a router that stores information about the routes to various network destinations. This table is crucial for the routing process because it enables routers to determine the best path for forwarding packets of data across a network. Each entry in the routing table typically includes the destination address, the next hop (next router address), and associated metrics that may include distance or cost to reach that destination.

By referencing the routing table, the router can make informed decisions about packet forwarding, ensuring efficient data transmission and proper network communication. This functionality is fundamental to the operation of IP networks and underpins the routing protocols that facilitate dynamic updates to the routing table based on network changes. The accuracy and up-to-date nature of the routing table is essential for efficient network performance.

The other options do not correctly define a routing table. For example, while a record of bandwidth usage across a network is important for network management, it is not related to routing. Similarly, a configuration file for all network devices pertains to device management rather than routing paths, and a list of available network applications does not involve routing details at all.
